Traynor Custom Special Bass Amplifier Stack (Head and Cabinet)

This is a vintage Traynor amplifier stack consisting of a vacuum tube head unit and a matching large-format speaker cabinet. The head unit is identifiable as the Traynor Custom Special, likely the YBA-3 model, which was a flagship bass amplifier produced by Yorkville Sound in Canada during the late 1960s to mid-1970s. Physically, the units are encased in rugged black Tolex-covered wooden enclosures with a signature silver-grey grille cloth and polished chrome-style trim accents. The head features a row of seven 'chicken head' or ribbed control knobs on a black brushed-metal faceplate, including inputs for high/low gain, volume, and a multi-band EQ section. The 'Traynor' logo is prominently displayed in a stylized silver script on a black background on both units. Notable for its 'overbuilt' construction, this model is historically significant for its high power output for the era and its reliability. Condition-wise, the grille cloth on the cabinet shows some light sagging or dust accumulation, and the Tolex exhibits minor scuffing consistent with age and use. The chrome trim on the edges appears mostly intact. The presence of the original carrying handle on the head and the overall cleanliness of the faceplate suggest a well-maintained piece of vintage musical equipment, valued for its warm, tube-driven harmonic saturation.
